  UK roundabout scene pack for AV simulators

  What it is

  Lancing Manor Roundabout compiled from open data (OpenStreetMap, OS Open Roads, Environment Agency LiDAR) into the files AV simulators load: OpenDRIVE, OpenUSD and NVIDIA's RDS-HQ scene format, with clockwise, left-hand lanes. A 1.13 MB pack you can download.

  What it found

  All eight checks set in advance pass: the ring turns clockwise, 75 of 75 lanes are valid, and 4 of 4 test cars complete in esmini (0 of 4 when switched to right-hand traffic, so the check is real). In CARLA one car first took a wrong exit; that was traced to CARLA's own traffic controller, not the pack, and that first fail stays on the page.

  Why it matters

  UK left-hand road geometry in the formats simulation tools read, for AV developers testing in left-hand countries and for simulation teams.

  Used

  • NVIDIA RDS-HQ
  • OpenUSD
  • ASAM OpenDRIVE
  • esmini
  • CARLA
  • MapMap scene compiler

  What each technology did here

  • NVIDIA RDS-HQ · NVIDIA

    The pack ships a complete RDS-HQ scene that matches the OpenDRIVE road to within 1 cm.

    NVIDIA's driving scene format (roads, lanes, objects and camera poses) that its simulation and world-model tools read.

  • OpenUSD · Open source and open standards

    The same scene as a USD stage.

    The open 3D scene format that Omniverse and many other 3D tools read.

  • ASAM OpenDRIVE · Open source and open standards

    The road network, lane by lane, validated by esmini and CARLA's reader.

    The open standard for describing road networks, lane by lane, that driving simulators load.

  • esmini · Open source and open standards

    4 of 4 test cars complete clockwise; 0 of 4 when switched to right-hand traffic.

    An open-source driving scenario simulator that loads OpenDRIVE roads.

  • CARLA · Open source and open standards

    Map reader agrees; a server run on 24 and 26 October traced a wrong exit to CARLA's controller, not the pack.

    The open-source driving simulator widely used in self-driving research.

  • MapMap scene compiler · MapMap

    Open map data to OpenDRIVE, OpenUSD and RDS-HQ.

    MapMap's compiler from open map data to the scene files simulators load: OpenDRIVE, OpenUSD and RDS-HQ.

  Where the Bikes End Up, Brighton

  What it is

  Brighton's hire bikes and e-scooters, collected every 2 minutes: where they are left outside bays, which bays overflow, and the morning van route that clears them.

  What it found

  At a typical refresh (the median, data from 21 to 26 Oct 2026), 50 of some 880 bikes and e-scooters are outside a bay, and 10 of 119 bays are over capacity. Anything that could point to someone's home is withheld: overnight stays on residential streets, side roads and lone spots on main roads.

  Why it matters

  A real UK fleet job on a real travel-time matrix, for councils that license hire bikes and e-scooters and the operators that rebalance them.

  Note: The route is solved by VROOM; NVIDIA cuOpt, run on the same saved instance, found the same plan, but one stop is too small to tell two solvers apart.

  Used

  • NVIDIA cuOpt
  • VROOM
  • MapMap travel-time matrix
  • Pre-registered tests

  What each technology did here

  • NVIDIA cuOpt · NVIDIA

    Run on the saved instance (same SHA-256) and the same MapMap matrix, on an NVIDIA A40: the same plan as VROOM, 22.5 minutes and 9.2 km, no rule broken. One stop leaves only one route, so it shows the run, not which solver is better.

    NVIDIA's GPU route optimiser for fleets and deliveries.

  • VROOM · Open source and open standards

    The morning route, solved through MapMap's hosted optimiser.

    An open-source route optimiser. MapMap's hosted optimiser runs it on MapMap's travel-time matrix.

  • MapMap travel-time matrix · MapMap

    Travel times between every bike and bay.

    MapMap's many-to-many travel times, the input every route optimiser needs.

  • Pre-registered tests · MapMap

    Definitions, tests and privacy withholding rules committed before any analysis.

    MapMap's method: the pass bar is written and hashed before the data is opened, and a failed test stays on the page.

  Surface Water on the GPU

  What it is

  The Surface Water Twin's solver, built for NVIDIA GPUs with Warp, run across 76 scenarios (recorded storms, design storms and ground-survey variations, each with and without drainage), then opened and path-traced in NVIDIA Omniverse.

  What it found

  All 76 scenarios finished, and the modelled water opens as an OpenUSD stage in Omniverse, now cut into a 43-second silent film. Our GPU build did not match our own CPU reference within the tolerance we set, so the page gives no speed figures.

  Why it matters

  A real storm on real UK terrain as a scenario set and a rendered scene, for highway drainage and asset teams, flood authorities and teams building physical AI on real ground.

  Note: The picture is rendered and the water depths are modelled; the lighting is illustrative.

  Used

  • NVIDIA Warp
  • NVIDIA Omniverse
  • OpenUSD
  • MapMap terrain pipeline

  What each technology did here

  • NVIDIA Warp · NVIDIA

    The solver's GPU build ran the whole scenario set on one rented NVIDIA RTX 6000 Ada.

    NVIDIA's Python framework for writing physics and simulation code that runs on a GPU, or on a CPU.

  • NVIDIA Omniverse · NVIDIA

    Omniverse Kit via Isaac Sim 6.1 opened the stage headless and path-traced the film.

    NVIDIA's platform for building and rendering 3D scenes. We open stages headless through Isaac Sim and path-trace them.

  • OpenUSD · Open source and open standards

    The terrain, road and water field exported as a USD stage.

    The open 3D scene format that Omniverse and many other 3D tools read.

  • MapMap terrain pipeline · MapMap

    The same Environment Agency ground as the Surface Water Twin.

    MapMap's pipeline that turns Environment Agency laser scans into road-level terrain.
